Description

Technical Field

[0001] The utility model relates to a device for preventing a D-beam reinforcement system from lateral movement. Background Art

[0002] In the existing technology, rails are usually not straight segments. When a train is traveling on a curve, it is necessary to provide a turning centripetal force. Usually, the height of the outer rail is higher than the height of the inner rail. This method makes the train slightly tilted so that the component of gravity can provide the centripetal force. However, after the line reinforcement is completed, the train is slowed down. The required turning centripetal force is much smaller than the centripetal force required for normal driving. The height difference between the inside and outside of the rails will not change, which will cause the component of the train's gravity to squeeze the inner rails. The rails are transmitted through the crossbeams and finally act on the longitudinal beams, which may cause the longitudinal beams to deform. The squeezing force on the D-beam is different at different slow speeds of the train. The original reinforcement method is to weld only a section of I-beam at the connection of the D-beam. Considering the poor flexibility of the I-beam, the lack of buffering capacity, poor anti-extrusion capacity, and easy fracture at the weld, the I-beam is replaced by an improved reinforcement device, which cannot cope with the changing force. If the blocking force is too small, the anti-lateral displacement effect will not be achieved. If the blocking force is too large, the rails will be squeezed inward. Summary of the invention
